Algae (both micro and macro) have gained huge attention in the recent past for their high
commercial value products. They are the source of various biomolecules of commercial applications
ranging from nutraceuticals to fuels. Phycobiliproteins are one such high-value low volume compounds
that are mainly obtained from micro and macroalgae. In order to tap the bioresource, a significant
amount of work has been carried out for large scale production of algal biomass. However, work
on downstream processing aspects of phycobiliproteins (PBPs) from algae is scarce, especially in the
case of macroalgae. There are many difficulties in cell wall disruption of both micro and macro algae
because of their cell wall structure and compositions. At the same time, there are several challenges in
the purification of phycobiliproteins.
The current review article focuses on the recent developments in downstream processing of phycobiliproteins
(mainly phycocyanins and phycoerythrins) from micro and macroalgae. The current status,
recent advancements and potential technologies (that are under development) are summarised in this
review article besides providing future directions for the present research area.
